Challenging leading scientific theories that claim that our senses report back objective reality, cognitive scientist Donald Hoffman argues that while we should take our perceptions seriously, we should not take them literally. From examining why fashion designers create clothes that give the illusion of a more "attractive" body shape to studying how companies use color to elicit specific emotions in consumers, and even dismantling the very notion that spacetime is objective reality, The Case Against Reality dares us to question everything we thought we knew about the world we see.

Cognitive scientist Donald Hoffman's exploration of the extraordinary creative genius of the mind's eye "has many virtues, of which sheer intellectual excitement is the foremost" (Nature). Hoffman explains that far from being a passive recorder of a preexisting world, the eye actively constructs every aspect of our visual experience. In an informal style replete with illustrations, Hoffman presents the compelling scientific evidence for vision's constructive powers, unveiling a grammar of vision - a set of rules that govern our perception of line, color, form, depth, and motion. Hoffman also describes the loss of these constructive powers in patients such as an artist who can no longer see or dream in color and a man who sees his father as an impostor. Finally, Hoffman explores the spinoffs of visual intelligence in the arts and technology, from film special effects to virtual reality. This is, in sum, "an outstanding example of creative popular science" (Publishers Weekly).
